Kinetic energy = 1/2 x mass x velocity²
10.0km x 100 = 10000m
Kinetic energy = 1/2 x 100 x 10000²
Kinetic energy = 5000000000J
Answer:
b. greater because the column of blood between the arm and leg has hydro-static pressure
Explanation:
The use of the "depth" equation explains it very well.
By definition, the mechanical advantage is the relationship that exists between the output force or load lifted and the value of the force applied.
Thus, using the definition, we have that the mechanical advantage is given by:
Therefore, the mechanical advantage of lifting the box by using a pulley is equal to 1.
Answer:
The mechanical advantage in this situation is:
Equal to 1
